12 Claims. (!.128-284'i The present invention relates to sanitary devices, and particularly to a substitute for diapers for babies.

Babies and small infants who have not yet i learned to control the passage of urine and movement of the bowels require some convenient sort of device to protect the bed linen and clothing. The conventional answer to the problem is the diaper, a cloth folded to fit the child comfortably, and of a semiabsorbent nature, so that it will hold the secretions until such time as it can be replaced by a fresh one.

Such diapers require frequent changing and very careful washing and sterilizing before being used again. The labor involved in caring for them is a heavy burden on those charged with the care of the child.

In hospitals or other establishments where large numbers of babies are cared'for together, the diapers require exceptionally thorough treatment to prevent the spread of various types of such as rubber, reinforced at necessary or condisease from one baby to another and from the outside. The problems of the household are multiplied when infants are cared for in institutions. A

The labor and inconvenience in the handling of diapers has lead to numerous attempts to devise a satisfactory substitute. Some recent eiiorts have been aimed at the employment of treated cellulose sheets which would be used but 1 been able to overcome the dimculty of maintaining the properalinement of the receptacle portions with the secreting organs-without uncomfortably constraining the baby. Further, the structures have been such that the cleansing of them has been provocative of more trouble than the conventional diapers. Again the harness or supporting strap system of such devices has been I complicated, objectionable and unduly restric tive.

Various other substitutes have been devised which are known to those familiar with the art, but all of them have been open to objections so serious as to prevent their wide-spread adoption.

The present invention comprises a yielding container made to receive the urine and fecal discharges and to hold them away from contact with the skin, particularly with reference to urine. The arrangement does not require, however, any elaborate'precautions to aline the receiving portions with the respective discharge organs of the baby, nor can they be easily twisted or pulled into such position that'the container will have its function impaired. It is preferable to make the device of a soft, impervious material venient places to maintain the desired shape,

and arranged to retain the discharged material without restricting the baby.

The details of the invention may be understood more fully by reference to the drawings 7 structure taken as indicated by line 5-5 in Fig. 3;

shown in Fig.

the embodiment of Fig. 2;

Fig. 9 is a fragmentary sectional view of a modified shape of rim;

Fig. 10 is a fragmentary sectional view of another rim structure.

From inspection of the drawings and from the description which follows, it will be seen that the primary object of the invention is to provide a satisfactory substitute 'for. a baby's diaper.

Some of the other objects are: to provide a receptacle for holding temporarily theurine and stool discharged by a baby; to provide a substitute for diapers which can be readily cleansed and disinfected; to reduce possibility of spreading infectious diseases throughdiaper contact; to prevent soiling of clothes and bed linen by involuntary discharges of urine and fecal matter; to provide a sanitary device which may be used by persons of any age who are afflicted with incontinence or lack of control of the bladder and bowels; to provide a sanitary substitute for a bed pan for those persons who are unable to make use of the conventional types; to provide an easily portable container for stools and urine which may be attached without discomfort to the user; to provide a diaper substitute which requires no elaborate harnesses for its support; to provide a diaper substitute which may be rials having great resistance to corrosive secretions; to provide a diaper substitute which re.-

- tains discharged matter out of contact with the the rear a preferred form of a device in position in Fig. 1, comprising a unitary rubber container I shaped to fit around the external urinary and fecal organs of the baby or-other, user, and to beheld in position by means such as a resilient belt '2 fastened'around the waist of the wearer l and attached to the container I by suitable clasps l at front and rear. The embodiment shown anteriorly in Fig. 2 will be explained lateri'in connection with Figs. 6 and'l.

\ Container I depends from a rim 8, molded of relatively heavy rubber or similar material shaped to fit snugly over the lower portion of Inner pouch I8 is pierced by a comparatively small number of'relatively large perforations IO. ,Through them' the liquid entering the inner pouch I is rapidly passed on to outer'pouch II,

which is urinary compartment B. The outer' pouch is also secured to, or formed integrally readily manufactured of easily procurable matewith, the rim 6, and is elongated both front and f rear therebeyond. The'purpose of such elongation is tomake sure that-regardless of theposition in which the baby is lying, a part of pouch II will lie below the trough 9 and pouch I5, thus ensuring a gravity drainage into the storage. or outer, pouch II. It will be seen that elongating the pouch II beyond a vertical line through the uppermost portions of rim 8 accomplishes this result. If the child is lying prone, the forward portion I! of the pouch" will be lower than trough 8; if supine, the rear portion 20' of the pouch II will lie beneath the trough;

while if upright, the entire pouch is in receptive position;

The provision of fewer apertures I6 between I5 andIl, and wider spacingthan the. users abdomen in front, as shown in Fig. 2,

around the crotch and over a substantial por- 'tion of the buttocks, as shown in Fig. 1. A

groove 1 maybe molded into rim 8, facing inwardly throughout'to provide a firm but yielding contact with the body of the user. when the rim i is pressed against the skin, groove 1 becomes a low pressure vacuum cup, tending to hold the rim more tightly to the 'body.- Two shoulders 8 lying on each side of the groove 1- are thus in position to act as sealing members.

From the rim 8 hangs an inner trough 9 of firm rubber or similar material having a large number of smallperforations Ill. These perforations may be distributed over the entire area. A diaphragm II may be set across the trough or pouch 9 somewhat forward of its median portion, dividing the pouch into a front or urine-receiving portion I2 and a rear faeces cradle portion I4. It is not essential that the device be used in such position that all the urine is deflected away from immediate contact with the faeces by the diaphragm I I. Hence the diaphragm II may be eliminated if desired. The numerous perforations I0 allow all of the liquid discharge to drain out of the trough 9 into urinary compartment A and thence into compartment B, while retaining the faeces in cradle I4.

The trough or pouch 9 may be formed integrally with the rim 6, or may be joined thereto by any method which will produce a liquid-tight connection, Adjacent the line of attachment between trough or pouch 9. and rim 6, the latter is joined by similar means to an inner pouch I5, which completely surrounds the trough or pouch 9, andreceives the liquid seepage therefrom.

Thus urinary compartment A is formed.

in the case of the trough and feces-cradle,.aeta -to confine the liquid matter to the outer compartment II. If compartment I'I 'becomes'over- 1? f there couldoccur a reverse flow in some positions, but suflicient capacity is provided so that under normal conditions there will be no return Likewise, it is contemplatedthat the device may be provided witlrsmall check valves placed "in the perforations I6 whiohprevent return flow.

under anyfi i A portion of pouch I1 is' re f threaded to forms. drain 2| for the removal of the liquid wastes and to permit ready .cleansing. -In use, drain 2| may be closed by a screw plug 22.

Additional reinforcements may be provided'to maintain the proper shape of the container, such as a rib 24 molded around the median line of -pouchJI. The feces cradle 9 may also be'reinent devicewotild eliminate the urine compartforced at the rear by ribs, not shown, or by using I a slightly stiffer material section to prevent the material from clinging too closely to the buttock area.

A simpler and less expensive form zof the prestachmentmay be provided.

From the description above it will be seen that a wide latitude is possible in the positioning of the device, since even if it is not in its normal location, the rim and the laterally enlarged front and rear portions will be in sealing position and capable of receiving alldischarges from the infant without danger of. spillage.

It will be observed that the device, by changing its dimensions, is equally suited to use by adults who require sanitary protection.

Referring now to the embodiment of Figs. '2, 6 and '7, there is illustrated an .embodiment which permits a smaller device to be used in cases where it is possible to support a holding con tainer by attaching it to a leg, for example, or

. bag.

Where portability is not desired and any kind of holding or disposal facility is available.

In this embodiment, a similar structure is used for the frame 8 and the pouch 9. Inner pouch 3B is made somewhat larger than in the previous embodiment and it may be desirable to form a larger number of drainage apertures 3| therethrough. These drainage apertures 3| may likewise be provided with small check valves to prevent possibility of return flow. Outer conduit 32 is formed along the median line of pouch 3B, and provides no storage space, but merely acts as a collecting conduit, leading the accumulated liquid wastes into front and rear discharge conduits 34 and 35 respectively. The conduits 34 and 35, which may be conventional rubber tubing, may be joined at will with a common conduit 35, in turn leading to a rubber bag 31 or other discharge container. If desirable, the bag 37 may be attached to the leg of the individual by straps 38 and a check valve 39 is provided to prevent the bag from being emptied back into the tube 36, while permitting gases to escape from the Such valves are known to the art, and a detailed description will not be given, since it forms no part of the instant invention. Obviously, a single conduit from the outer pouch 32 might be used, but I prefer to have both front and rear outlets to insure rapid drainage in either the prone, supine or erect positions.

In some devices it may be advantageous to use a sponge rubber construction for the rim 6, but

' any suitable material may be used. The shape of the rim may be varied also. Fig. 9 shows a rim having a single rounded rib 80 instead of the grooved type shown in Fig. 8. I have also found a wedge-shaped or triangularly beaded rim ll, as shown in Fig; 10, to be. satisfactory. Particularly in those cases where a softer material is used for the rim, a coredZ of wire or other material may be molded in to hold the desired contour of the rim and shape it to the body of the user.

The upper compartment or trough 9 may be provided with a highly absorbent material such as cellulose for containing the greater mass of urine and fecal discharges. The form is preferably a disposable pad shaped to fit the entire compartment or if the diagram H is employed then'the disposable pads would be shaped to fit the individual compartments. The urine containers such as A and B would provide capacity for the extra urine not capable of being absorbed by the pad.

The pads of absorbent material may be treatedwith an antiseptic or deodorant, such as boric acid (powder), and can be manufactured'for economical use. With the use of such pads, some convenience may be added for employment of the requires a minimum of harnesses to support it.

and thus prevents one of the causes of chafing and irritation.

It is useful not only for babies, but also for those older children or adults who are unable to exercise control over their eliminative functions or who are confined to bed and find it difiicult to use the ordinary sanitary devices.

The use of my device relieves the mother or at-- upon which he may have supposedly selected the \words of this disclosure nor possible for any human to anticipate what direction the future development of the art may take, which may make the language used inapt. Therefore, the disclosure of this invention should not be construed as limited by the words used and, further, the substance should not be confined to the precise forms in the drawings illustrating this invention. It is contemplated that changes of form may be made, with variations and departures from the illustrated forms, without departing from the scope of this invention. Such variations and departures include those made possible by discovery of improved materials and better uses and forms of present materials, as well as practices and results which may be possible in actual commercial fabrication and handling.
